Utterly bizarre theoretical 'fractons' could be made for real

Atoms arranged in particular shapes inside crystals are similar to theoretical particles called ‘fractons’

Exotic theoretical particles known as fractons have until now remained imaginary constructs. But new research suggests they may have been lurking under our noses within a certain kind of defect in crystals. The findings could one day help us build memory storage for quantum computers.

In 2011, Jeongwan Haah, then a graduate student at the California Institute of Technology in Pasadena, California, discovered a new theoretical phase of matter composed of particle-like entities he dubbed ‘fractons.’
